Frame Retry Rate exceeded
This trap refers to the event when the percentage of received and transmitted frames with the retry bit crosses the high water mark. This event can be triggered for an AP, a station, or a channel. The two values that should be configured related to this event are "Frame Retry Rate - high water mark" and "Frame Retry Rate - low water mark". The high water mark refers to the percentage threshold that, if surpassed, triggers the event that causes the trap to be sent. The low water mark refers to the percentage
Thresholds such that if the retry rate reaches a value lower than this value the event is reset. What this means is that the trap will be triggered the first time the Frame Retry Rate crosses the high water mark and then will only be triggered if the Frame Retry Rate goes under the low water mark and then crosses the high water mark again.
Frame Low Speed Rate exceeded
This trap refers to the event when the percentage of received and transmitted frames at low speed (less that 5.5 Mbps for 802.11b and less that 24 Mbps for 802.11a) exceeds the configured high water mark.
